Electronic Upcycling of Corn Straw: Biobased Elastic Conductive Cross-linked Network Eco-friendly Hydrogels with multifunction for Flexible Wearable Sensors

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Published: June 11, 2024

The conductive hydrogels based on biomaterials have garnered much attention. However, the utilization of corn straw, an agricultural waste, as a gel substrate can achieve recycling agro-waste and development advanced electronic materials, which has dual benefit strategy seems to be overlooked. In this study, straw pith (CSP) multifunctional hydrogel (CSP-MCG) was prepared by introducing CSP, presents oxygen-rich groups, into three-dimensional crosslinking network system hydrogel. CSP-MCG mechanical elasticity (maximum tensile rate 340%) responsiveness external environmental factors (mechanical strain, temperature, humidity): Under different strain conditions, fatigue response is stable sensitivity high (GF=2.8, R2=0.996, Tres=0.075s);In temperature range 20℃-50℃, it exhibits great performance (R2=0.993, TCR=1.34%/℃, Tres=0.5s); Within humidity RH29%-79%, signal changes steadily time short (Tres=0.2s). addition, not only various stimuli, but also demonstrates ability differentiate between these stimuli variation trend in its resistance capacitance. Due exceptional multi-functional sensing capabilities attribute (recyclability degradability), green flexible material practical applications such skin, human-computer interaction wearable sensors.
